KNIFE-GAGE FOR HEEL-TRIMMING MACHINES.

SPECIFICATION forming part of Letters Patent No. 319,465, dated June 9, 1885.

Application filed March 2, 1885. (No model.)

To all whom it may concern.-

Be'it known that I, GEORGE W. DE LAND, of North Brookfield, in the county of Worcester, State of Massachusetts, have invented a certain new and useful Improvement in Knife- Gages, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a side elevation of my improved gage detached from the knife; Fig. 2, a top or plan view of the stock with the cap, slide, adj Listing-screw, and friction-stud removed; Fig. 3, a plan View of the slide; Fig. 4, a vertical transverse section taken on line we in Fig. 2, the adjustingscrew being represented as in position; Fig. 5, a vertical transverse section taken on line 3 g in Fig. 2, the friction-stud being represented as in position; Fig. 6, a perspective view representing the gage attached to the knife and the knife mounted in its stock or holder, and Fig. 7 a perspective view of the knife detached.

Like letters of reference indicate corresponding parts in the different figures of the drawings.

My invention relates to that class of knife gages which are employed with knives of the McKay boot and shoe heeling machines; and it consists in a novel construction and arrangement of the parts, as hereinafter more fully set forth and claimed, by which a more effective and otherwise desirable article of this character is produced than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the stock, which is provided with an adjusting-screw, B, and set-screw G, for adjusting and securing the gage on the knife in the usual manner.

Projecting laterally from the stock A there is an arm, 1), provided with a cap, E, and centrally-disposed vertical hole m. Said arm rises considerably above the plane of the stock, and is provided with a lateral slot, (1, opening into the hole m.

A slide, H, having its outer side properly.

curved and its inner side provided withthe laterally-projecting flange J, is fitted to slide vertically on the arm D, said flange being adapted to work in the slot d, and having its outer end enlarged, as seen at z, to fit the hole m.

An adjusting-screw, K, is fitted to rotate in the cap E, but not to be withdrawn therefrom, being provided with an annular flange, Z, beneath said cap. The enlarged portion 2 of the flange J is provided with a vertical hole, h, which is threaded to receive the screw K.

A hole, N, is also formed in the arm D, and disposed in said last-named hole there is a sliding rod, Q, provided with a spring, i, said rod being enlarged at its upper end and adapted to engage the flangel 011 the screw K and by friction prevent said screw from accidentally turning.

The knife 0, which is of the ordinary form and construction, has its lower end attached to a block, P, mounted in the adjustable stock or holder T, and provided with a spring, W, in the usual manner. The gage is mounted on the arm f of the knife, said arm working in a transverse dovetailed slot in the lower side of the stock A, and being provided with a groove, W, for receiving an annular flange on the adjusting-screw B, so that when said screw is turned in or out, its flange being in said groove, the gage will be withdrawn or advanced,as the case may be. The slide I-Iis designed to press against the upper of the shoe, and passes down over the cutting-edge g of the knife, as shown in Fig. 6, to protect the upper from injury thereby.

In the use of my improvement the stock A is first adjusted on the knife by the screw 13 and secured in position by the screw 0, after which the slideHis moved into any desired position by the screw K, or adjusted to a greater or less height relative to the knife, in accordance with the width of the heel and the manner in which it is to be shaved.

It will be obvious that the gage may be readily adjusted with the greatest nicety, consists ofvery few parts, is strong, durable, not liable to get out of order, and is adapted for all classes of work.

Having thus explained my invenlioi, what I claim is- 1. In a gage for the knife of a -heeling-n1achine, the combination of the following instrumentalities, to wit: a stock, an adjustingcrew for adjusting the stock on the knife, a

5 set screw for securing the stock in any desired position on the knife, a vertically-adjustable slide adapted to press against the shoe when in use, an adjusting-screw for said slide, and a friction device or means for holding said slide in position when set, substantially as described.

2. In a gage for the knife of a heeling-machine, the stock A, provided with the arm D,

slide H, screw K, and means for keeping said slide in position when set, substantially as set- -forth.

3. In a gage fort-he knife of a heeling-machine, the screw K, provided with the flange Z, in combination with the cap E, spring-rod N, and slide H, substantially as described.

4. The improved knife gage herein described, the same consisting of the stock A, provided with the screws B 0, arm D, and cap E, the screw K, provided with the flange Z, the rod Q, provided with the spring t, and the slide H, provided with the flange J, constructed, combined, and arranged to operate substantially as set forth.

5. A gage for heeling-machines provided with the adjustable slide H, having the pro- 0' jecting flange, in combination with a knife for paring or shaving the heel and means for adjusting and securing the gage on the knife, substantially as described.
